Shorting Oil as Copper Breaks Support

In my previous post (https://www.tradingview.com/v/oUqeWN0O/), i was waiting for a confirmation to short oil as copper has lead oil lower. I am looking for leg lower in oil price.

Trade number: 68
Accumulated profit/loss (pips) = 2472

Pre-trade stats:
Winners: 34 Losers: 22 Cancelled: 10
Profit/loss (in pips) = 2472
Open trades: 1 Pending trades: 1
Trading Criteria:
1. Trades are taken in two units
2. First unit would be closed at first target
3. Stop loss is moved to breakeven
4. Second unit at second target
5. If 90 percent of first target is reached without triggering entry, trade is cancelled

Hi Technician, great analysis on the charts. Keep up the good work!
One question regarding your trades: do yo u have a predefined target in terms of risk/reward ratio (1:2, 1:3, etc.) or do you just let it go to the next bigger support/resistance area? Thanks
